Honeybees use scent marks while foraging. When collecting nectar and/or pollen, foraging honeybees scent mark nectar-producing flower by depositing attractive pheromones to signal to other honeybees of a nearby rewarding food source. Honeybees also use a short-lived repellent scent mark that identifies exhausted and recently visited rewarding flowers not yet replenished with nectar. Subsequently visiting honeybees detect and avoid these nectar-depleted flowers. Over time, as nectar replenishes in the flower, the repellent scent mark fades until gone and the flower is eventually revisited by another foraging honeybee. It is presumed that the use of repellent scent marks increases foraging efficiency by reducing the time spent probing nectar-depleted flowers.

The repellent scent mark used by honeybees is 2-heptanone. Produced and secreted by the mandibular glands of adult worker honey bees, 2-heptanone is known as the alarm pheromone because under certain circumstances elicits aggressive behavior in honeybees when detected. Honeybees detect 2-heptanone using an olfactory pathway mediated by a specific odorant-binding protein called OBP2. By taking advantage of its properties, repellent formulation of 2-heptanone have been produced and used in agricultural settings. For example, 2-heptanone has been applied to crops in order to repel honeybees away from areas where toxic insecticides have also been applied, thereby reducing honeybee mortality and avoiding potential insecticide contamination of the colony and the hive products obtained thereof. However, such uses have had very limited success primarily because 2-heptanone is a considerably volatile compound, having an effective half-life of only a few hours. As such, 2-heptanone is impractical and cost-ineffective for agricultural uses because of the extensive efforts necessary to apply and maintain an effective amount of this repellent in the treated area.

Therefore, what are needed are more effective honeybee repellents that exhibit repellent properties similar to 2-heptanone, but are less volatile. The present specification discloses such honeybee repellents and uses and methods for such compounds. The disclosed honeybee repellents will benefit apiculture since honeybees are a crucial, domesticated species that is threatened by routine agricultural practices such as the use of insecticides.

Thus, aspects of the present specification disclose honeybee repellents exhibiting repellent properties similar to 2-heptanone, but are less volatile than 2-heptanone.

Other aspects of the present specification disclose a use of a honeybee repellent disclosed herein to repel a honeybee from a location treated with the honeybee repellent. In one embodiment, the disclosed use is a use of a honeybee repellent disclosed herein to repel a honeybee from foraging and/or collecting nectar from a flower of a plant treated with the honeybee repellent. In another embodiment, the disclosed use is a use of a honeybee repellent disclosed herein to repel a honeybee from a structure treated with the honeybee repellent.

Yet other aspects of the present specification disclose a method of treating a location by applying a honeybee repellent disclosed herein, wherein the application repels a honeybee from the treated location. In one embodiment, the disclosed method is a method of treating a plant by applying a honeybee repellent disclosed herein, wherein such application repels a honeybee from foraging and/or collecting nectar from a flower of the treated plant. In another embodiment, the disclosed method is a method of treating a structure by applying a honeybee repellent disclosed herein, wherein such application repels a honeybee from the treated structure.

DESCRIPTION

Honeybees are maintained by humans in order to harvest honey, beeswax, and other hive products produced by these insects for commercial markets. In the United States, for example, honeybees produce $270 million worth of honey, beeswax, and other hive products. Besides the economic importance of hive products, honeybees are critically necessary to pollinate many important agricultural crops produced worldwide. For example, honeybees pollinate over $14 billion worth of crops annually in the United States. As such, promoting and maintaining honeybee survival is of great economic importance.

Insecticides are widely used to increase the yields of agricultural crops and their use is one of the major factors behind the increase in agricultural productivity in the 20th century. However, there is an inherent tension between the use of insecticides on crop plants to control invading pest insects and the necessity of honeybees to pollinate these same plants and the economic importance of hive products. One commonly used method is to delay the use of insecticides until the honeybees pollination has occurred, and then apply the insecticide. However, foraging for nectar occurs throughout the growing season, and as such, foraging honeybees are still exposed to the insecticide. Furthermore, recent evidence suggests that commonly used nicotine-based insecticides like Clothianidin and Imidacloprid may be a causal factor in colony collapse disorder, a phenomenon in which worker honeybees from a colony abruptly disappear. As such, it would be extremely beneficial to develop and use compounds and methods of insect control that minimize honeybee mortality.

Although of significant value, honeybee pollination can also cause economic harm to certain agricultural crops. For example, certain seedless citrus fruits like seedless tangerines, grapefruit, and mandarin oranges are of great economic value due to consumer preference. These seedless fruits are self-pollinating. However, if honeybees cross-pollinate the crop plants with the pollen of a seeded citrus fruit, then these citrus fruits will develop seeds and become undesirable to the consumer. As such, citrus fruit growers employ insecticides in order to prevent honeybee cross-pollination. The most common insecticides used for this application are neonicotinoids like Clothianidin and Imidacloprid, which as discussed above, appears to be a causal factor in colony collapse disorder. One problem with this approach is that the nectar collected by honeybees from the flowers of citrus trees produces a flavorful and economically desirable honey. As such, beekeepers have historically kept colonies near citrus orchards. Thus, there is another inherent tension between the economic importance of hive products produced by honeybees versus the financial harm caused by honeybee pollination in certain agricultural crops like citrus trees. As such, it would be extremely beneficial to develop and use compounds and methods that could repel honeybees from crop plants where pollination is undesired without causing significant honeybee mortality.

Insect chemosensory proteins (CSPs) regulate or control crucial behaviors. The chemosensory system consists of several chemosensory protein (CSP) classes. Chemosensory protein classes that are important in the design of novel insect control products include soluble proteins found in the antennal hemolymph and the maxillary palps, such as odorant binding proteins (OBPs) and sensory appendage proteins (SAPs). OBPs and SAPs are carrier proteins that facilitate the transport of external stimuli such as odor molecules through the aqueous hemolymph of sensory appendages to the surfaces of neuronal cells. There, the protein/odorant molecule complexes bind G-protein coupled receptors (GPCRs) and initiate a signaling cascade that results in a behavioral response to the external odor or stimulus. Insects use chemosensory cues from the environment to control critical behaviors, such as feeding and mating. Thus, insect chemosensory proteins are promising targets for the discovery of novel insect control products based on manipulating insect behavior.

The present specification discloses improved honeybee repellents and uses and methods for such repellents. By exploiting the OBP2 olfactory pathway used by 2-heptanone, more effective repellent compounds have been identified and isolated. As such, the repellents disclosed herein manipulate the honeybees' chemosensory system by eliciting an avoidance response similar to the one initiated by 2-heptanone. The repellents disclosed herein are intended for agricultural, commercial, and consumer use. For example, the honeybee repellents disclosed herein are useful to repel honeybees from areas where insecticides have also been applied in order to reduce honeybee mortality and avoid insecticide contamination of honey, beeswax, and other hive products. As another non-limiting example, the honeybee repellents disclosed herein are useful to prevent unwanted pollination of plants by honeybees in crops where such pollination reduces the market value due to the resulting seeded fruits. As yet another non-limiting example, the honeybee repellents disclosed herein are useful to keep away honeybees from outdoor areas where human activities are occurring and would be disrupted by honeybee presence, such as, e.g., an outdoor activity like a sporting event or picnic. Similarly, the honeybee repellents disclosed herein are useful to keep away honeybees from man-made structures in order to prevent infestation of a colony, such as, e.g., a commercial building, a house, a shed, or other structure. Other uses of the honeybee repellents disclosed herein are discussed below and are readily apparent to a person of ordinary skill.

A honeybee repellent may preferentially bind, without limitation, an odorant Binding Protein 2 (OBP2). OBP2, also known as ASP2, refers to a soluble, acidic protein of about 13-16 kDa that is expressed in sensory tissues of honeybees. This protein binds 2-heptanone and escorts this compound across the hydrophilic extracellular matrix to the cell surface, where odorant receptors are located. Exemplary honeybee OBP2s include, without limitation, Apis mellifera OBP2 (SEQ ID NO: 1) and Apis cerana OBP2 (SEQ ID NO: 2). For a general review see, e.g., Dani, et al., Mapping the Expression of Soluble Olfactory Proteins in the Honeybee, J. Proteome Res. 9(4): 1822-1833 (2010); Pelosi, et al., Soluble Proteins in Insect Chemical Communication, Cell. Mol. Life Sci. 63(14): 1658-1676 (2006); Calvello, et al., Expression of Odorant-Binding Proteins and Chemosensory Proteins in Some Hymenoptera, Insect Biochem. Mol. Biol. 35(4): 297-307 (2005), each of which is hereby incorporated by reference in its entirety.

A honeybee repellent disclosed herein may be characterized by it binding affinity. Binding affinity can be described by an equilibrium dissociation constant (KD), which is defined as the ratio Kd/Ka at equilibrium; where Ka is the association rate constant of the repellent compound and kd is the dissociation rate constant of the repellent compound. Binding affinity is determined by both the association and the dissociation and alone neither high association or low dissociation can ensure high affinity. The association rate constant (Ka), or on-rate constant (Kon), measures the number of binding events per unit time, or the propensity of the repellent compound and the honeybee OBP to associate reversibly into its repellent-OBP complex. The association rate constant is expressed in M⁻¹ s⁻¹. The larger the association rate constant, the more rapidly the repellent compound binds to its honeybee OBP, or the higher the binding affinity between repellent compound and honeybee OBP. The dissociation rate constant (Kd), or off-rate constant (Koff), measures the number of dissociation events per unit time propensity of a repellent-OBP complex to separate (dissociate) reversibly into its component molecules, namely the repellent compound and the honeybee OBP. The dissociation rate constant is expressed in s⁻¹. The smaller the dissociation rate constant, the more tightly bound the repellent compound is to its honeybee OBP, or the higher the binding affinity between repellent compound and honeybee OBP. The equilibrium dissociation constant (KD) measures the rate at which new repellent-OBP complexes formed equals the rate at which repellent-OBP complexes dissociate at equilibrium. The equilibrium dissociation constant is expressed in M, and is defined as Koff/Kon=[L]×[R]/[L+R], where [L] is the molar concentration of the repellent compound, [R] is the molar concentration of the honeybee OBP, and [L+R] is the molar concentration of the repellent-OBP complex, where all concentrations are of such components when the system is at equilibrium. The smaller the equilibrium dissociation constant, the more tightly bound the repellent compound is to its honeybee OBP, or the higher the binding affinity between repellent compound and honeybee OBP.

One type of controlled-release device is a “reservoir” device where a honeybee repellent or composition forms a core surrounded by an inert diffusion barrier. An inert diffusion barrier includes membranes which are non-porous, homogeneous polymeric films, through which transport occurs by a process of dissolution of the permeating species in the polymer at one interface and diffusion down a gradient in thermodynamic activity. These membranes are usually referred to as solution-diffusion membranes. Another class inert diffusion barrier includes the porous and/or fibrous barriers such as, for example, hollow fibers, porous and/or fibrous materials, in which a repellent compound diffuses mainly by capillary forces. Other less common reservoir devices are designed to enable diffusion to take place by mechanical pumping or under external forces, such as, e.g., gravity, electrical field, vacuum, or centrifugal forces. A reservoir device can exist in a variety of shapes, and can be degradable or non-degradable.

In an aspect of this embodiment, a reservoir device is a microcapsule comprising a core of a honeybee repellent or composition disclosed herein surrounded by a coating or shell of, e.g., a polyvinyl chloride (PVC)-polyvinyl acetate (PVA) plastic. Size typically varies from about 1 μm to about 1000 μm and can have irregular or geometric shapes. Core payload usually varies from 0.1 to 98 weight percent. Encapsulation processes are often loosely classified as either chemical or mechanical. Examples of chemical processes include but are not limited to complex coacervation, polymer-polymer incompatibility, interfacial polymerization in liquid media, in situ polymerization, in-liquid drying, thermal and ionic gelation in liquid media, desolvation in liquid media, starch-based chemistry processes, trapping in cyclodextrins, and formation of liposomes. Examples of mechanical processes include but are not limited to spray drying, spray chilling, fluidized bed, electrostatic deposition, centrifugal extrusion, spinning disk or rotational suspension separation, annular-jet encapsulation, polymerization at liquid-gas or solid-gas interface, solvent evaporation, pressure extrusion or spraying into solvent extraction bath.

Another type of controlled-release device is a “monolithic” device where a honeybee repellent or composition is dissolved or dispersed throughout a substantially inert matrix from which the repellent compound and/or other beneficial compound is gradually released. Non-limiting examples of matrices included in a monolithic device include various gels, waxes, gelatins, natural resins, rubbers, elastomers, synthetic and natural polymers. A monolithic device can exist in a variety of shapes, and can be degradable or non-degradable. Size can vary depending on the application. For example, a monolithic device can be produced as a microcapsule having a size of about 1 μm to about 1000 μm with irregular or geometric shapes. As another example, a monolithic device can have a size of about 1 mm to about 10 cm with irregular or geometric shape.

A controlled-release device disclosed herein can be a liquid composition or a solid composition. A liquid sustained-release formulation includes a honeybee repellent or composition disclosed herein, a solvent, and typically further comprise surface active agents to render the composition readily dispersible in water, such agents include a wetting agent, an emulsifying agent, or a dispersing agent. In one embodiment, a liquid form of a sustained-release formulation is an emulsion formulation, such as, e.g., a water in oil (w/o) emulsion or oil in water (o/w) emulsion. Non-limiting examples of oils include vegetable oils and mineral oils. Droplet size can vary from the nanometer scale (colloidal dispersion) to several hundred microns. A variety of surfactants and thickeners are usually incorporated in the formulation to modify the size of the droplets, stabilize the emulsion, and modify the release.

A solid form of controlled-release device comprises a solid substrate like porous particulates such as silica, perlite, talc, clay, pyrophyllite, diatomaceous earth, gelatin and gels, polymers (e.g., polyurea, polyurethane, polyamide, polyester, etc.), polymeric particles, or cellulose.

EXAMPLES

The following non-limiting examples are provided for illustrative purposes only in order to facilitate a more complete understanding of the disclosed subject matter. These examples should not be construed to limit any of the embodiments described in the present specification, including those pertaining to the compounds, compositions, pharmaceutical kits, methods or uses of repelling honeybees.

Example 1 Testing of Candidate Compounds Using Binding Assay

To identify a honeybee repellent disclosed herein, candidate compounds were screened based upon the fact that 2-heptanone is an established repellent of bees. 2-heptanone is thought to mediate its behavioral response through binding to a specific odorant-binding protein called OBP2. Therefore compounds that bind OBP2 have the potential to act as odor “mimics” of 2-heptanone. By utilizing a fluorescent-quench, ligand-protein-binding assay, 30,000 compounds from the DIVERSET® library (ChemBridge Corp., San Diego, Calif.), a chemical library, were screened and over 150 candidate compounds were isolated that bind OBP2 (Table 1). Such assays are generally known in the art. See, e.g., Briand, et al., Ligand-Binding Properties and Structural Characterization of a Novel Rat Odorant-Binding Protein Variant, Eur. J. Biochem. 267(10): 3079-3089 (2000); Briand, et al., Ligand Binding and Physico-Chemical Properties of ASP2, A Recombinant Odorant-Binding Protein From Honeybee (Apis mellifera L.), Eur. J. Biochem. 268(3): 752-760 (2001); Briand, et al., Characterization of a Chemosensory Protein (ASP3c) from Honeybee (Apis mellifera L.) as a Brood Pheromone Carrier, Eur. J. Biochem. 269(18): 4586-4596 (2002), each of which is hereby incorporated by reference in its entirety.

Example 2 Testing of Candidate Compounds Using the PER Assay

To determine whether a living honeybee can recognize a candidate compound, these compounds were tested using a proboscis extension response (PER) assay using classical conditioning approaches. Proboscis extension response conditioning is a case of appetitive learning, in which bees learn to associate odor stimuli with sucrose reward in the laboratory. In this case, bees were conditioned to produce a PER to 2-heptanone as the conditioned stimulus and a sugar reward as the unconditioned stimulus. These trained bees were then exposed to an odor pulse of a candidate compound to test whether a candidate compound would also produce a PER. If the candidate compound “mimics” 2-heptanone then the honeybee will extend its proboscis.

For conditioning procedures, Apis mellifera Carniolan foraging worker honeybees were obtained from a local apiary (typically 60 bees per shipment). The honeybees were held overnight in insect cages with food and water freely available, in an environmentally controlled room on a light cycle similar to the ambient cycle at the time of the assay.

For conditioning procedures, all tests were done in an odorant delivery apparatus set inside a fume hood. The apparatus comprised a set of open-ended, horizontal, 3 cm diameter by 10 cm long plastic tubes. Each tube was designed where a honeybee could be positioned at the distal end of a tube, with the opening at the other end of the tube located proximal to an inlet of the fume hood. To deliver an odorant, room air was pumped by a diaphragm pump through a particle filter via 0.25 inch plastic tubing at approximately 0.7 m/sec. The air flow passes into the headspace above an odorant (0.5% [v/v] 2-heptanone dissolved in odorless light paraffin oil) contained in a 100 mL bottle. The headspace air then passes through another plastic tube to a manifold of 4-way valves, each of which was attached near the proximal end of a plastic tube containing a bee. Each bee was exposed separately for a desired time period to the odorant by opening and closing the appropriate valve. When each valve was closed, the odor was flushed away immediately by the continuous fume hood air stream.

To train a honeybee to respond to a conditioned and unconditioned stimuli, bees were placed, without anesthesia, in individual 1.5 mL micro-centrifuge holding tubes and held overnight without access to food or water. The holding tubes containing the starved bees were placed in racks in groups of eight. One rack at a time was placed behind the odorant delivery apparatus so that each bee's head is centered at the distal end of a horizontal plastic tube. Each bee was exposed to the 2-heptanone odorant alone for four seconds, and then while being fed an 80% sucrose solution for and additional three seconds. The sucrose solution was delivered on a piece of saturated filter paper held in forceps. The wet paper was touched to the bee's antennae if the bee did not immediately extend its proboscis (which usually happens in a fraction of a second after the sucrose solution comes near the bee's head). Positive and negative responses were recorded. A positive PER was scored when a bee extended its proboscis before the sucrose appeared. In a typical trial, 48 individual bees were subjected to conditioning. Six rounds of training were done before testing began, and typically a majority of the bees were successfully conditioned by the second or third round of training.

After conditioning, honeybees were tested with the candidate compounds the same day or on the following day or, most commonly, both. When held overnight, bees were fed with sucrose and kept in their holding tubes. When tested the day after training, bees were given one or more rounds of conditioning with 2-heptatone to refresh their memories. Candidate compounds stocks were made at 5% (w/v) in polyoxyethylene octyl phenyl ether (TRITON®X-100), a non-ionic detergent/surfactant, and stored at 4° C. This detergent is similar to substances used as carriers for a variety of commercial pest-control agents, can act as a solvent for both hydrophilic and hydrophobic substances, and is itself nearly odorless. Test solutions were made fresh daily by mixing stock solutions with water for a final compound concentration of 0.5%. A solution of 0.5% 2-heptanone in paraffin oil was used as a positive control. Both water and 15% polyoxyethylene octyl phenyl ether (TRITON®X-100) in water served as negative controls to eliminate false positives.

For candidate compound testing experiments, a single 3 cm length of 3 cm diameter plastic tube is positioned horizontally in a holder so that air is drawn through it at about 0.7 m/sec. Holding tubes containing a trained honeybee were positioned in racks as for the conditioning procedure. The rack was then moved sequentially behind the tube so that each bee's head was directly behind the rear end of tube for the test. The test compounds and controls were presented on a saturated piece of filter paper held at the front end of the 3 cm tube. Bees in each rack were exposed sequentially to a given candidate compound or control for four seconds and the results recorded. After bees were tested with one compound, the process was repeated for the next candidate compound using a clean tube and testing implements. The order of testing was randomized for each day's test and generally 5-6 different candidate compounds were tested in a single day along with 3 controls. Only bees giving a PER with 2-heptanone, but not with the negative controls were counted in calculating the percent of bees testing positive to each compound (Table 2). Generally about half of the total bees subjected to conditioning exhibited a PER with the 2-heptanone positive control, and only a very small number of these respond to the negative controls. If a given cohort of bees were tested for two consecutive days, they were tested with two separate sets of candidate compounds to maximize the number of individual bees tested with each compound. In a few cases where a single cohort of bees was tested twice with the same compounds. In this case, the results were averaged and the average was used in the calculation of the percent of positives. Table 2 shows results from PER assays for 66 candidate compounds.

Example 3 Testing of Candidate Compounds Using Choice Test

To determine whether living honeybees will choice to move towards a source of a candidate compound, these compounds will be assayed using a choice test in a free-flight box apparatus.

All tests will be done in a free-flight box apparatus. The apparatus comprises a 244 cm long×46 cm deep×30 cm high clear plastic box including two equally-sized independent testing chambers, each with 10 cm diameter air inlets that admit filtered room air, separated by a smaller central chamber with a screened air outlet to each testing chamber. Air can be pulled through the sealed box via a 10 cm diameter duct from the air outlet using an AQE Fume Fighter 500 fume extractor (BPA Air Quality Solutions, LLC, Charleston, S.C.), which removes the test odors using activated charcoal and HEPA filters. The box is housed in an environmentally controlled room with overhead illumination timed to correspond to the current ambient light cycle including 2 additional sets of lights timed to approximate crepuscular lighting conditions. The bottom of the apparatus will be lined with clean absorbent paper marked with a 4×9 grid pattern, forming 12 cm×12 cm squares with marked coordinates.

Apis mellifera Carniolan foraging worker honeybees will be obtained from a local apiary (typically 60 bees per shipment). Thirty honeybees will be put into each testing chamber and will be allowed to acclimate for 24 hours with food and water freely available. At the beginning of each test day all food will be removed from the test chamber, but water will be continually available throughout all tests. For each test, approximately 0.3 g of organic, raw orange blossom honey will be added to each clean small plastic weigh boat (Cole-Palmer). The honey boats will be placed in small plastic culture dishes, which will be distributed in the marked squares in the chambers. The positions of the dishes on the grid for a set of trials was chosen to avoid bees' preferred resting area so that they will have to find the food actively, but the same dish positions will be maintained for a given set of trials. We will use seven dishes of honey: six to which the bees will have access and a seventh that will have a screened lid. The honey in each boat was weighed on an analytical balance before and after the test, with the screened sample as a control for evaporative loss. The fume extractor was left off during the experimental trails, and was turned on to clear the air after the test dishes were covered and removed from the chamber at the end of each trial.

Based on the observation that bees tend to return to dishes in the same position where they have fed before, each set of trials with each group of bees began with “Pattern Identification” tests to see which dishes lose the most weight, reflecting the most feeding. Once bees are consuming an acceptable amount in 10-15 min, typically in 1-2 trials, a set of test compound trials will begin. The test compound will be pipetted onto pieces of filter paper placed on the dish bottom below the boat containing a fresh, weighed honey sample so that the test compound will be inaccessible to the bees. We used 2 μL of a candidate compound at a concentration of 0.05-0.5%, in Triton X-100 or paraffin oil, on each of four pieces of filter paper per dish. The test-solution dishes will be set at the same positions as the one or two dishes favored in the preceding Pattern Identification trial. To eliminate interference from the solvent, the other dishes without the test substance will contain the same volume of the appropriate solvent on filter papers as the test solution dishes. The bees will be allowed to feed for 10-15 minutes. Bee movements will be recorded by a small, wide-angle digital video camcorder (HD Hero 960; GoPro, Halfmoon Bay, Calif.) placed on a tripod in front of the test chamber. The bees will be given a brief rest while the honey will be weighed and a second test will be begin with fresh dishes, except that the test compound-containing dish or dishes will be placed at whichever positions were most visited in the preceding test. Tests will be continued until the bees' feeding slowed significantly, typically in 2-4 trials. The bees will be then rested for 1-3 hours and a subsequent set of trials begun with another Pattern Identification. Tests were performed in both chambers simultaneously, with the same test compounds. Groups of bees can perform as many as nine tests in one day, with an average of about seven on the first day and somewhat fewer on subsequent days, usually for three days.

To validate the test system, the known honeybee repellent, 2-heptanone, at the concentration used in the PER assays was used as a positive control for repellency. In addition, neroli oil, a component of commercial honeybee attractants (swarm lures), will be used as a positive control for an attractant. Lastly, a dish containing food alone will be used as a control for the components in the solution minus the candidate compound. Candidate compounds with high PER scores as well as compounds with lower PER scores will be examined in order to correlated the results from the choice test. Using the criterion of reduction of feeding at dishes that are most visited in the preceding test, candidate compounds with high PER scores attracted honeybees as well as, or better, than 2-heptanone as repellents, while weaker performers in the PER assay are generally less effective repellents.

To determine whether a compound has an effect on the bees in the free flight box, we calculated the likelihood of bees returning to a dish that they had exhibited a preference for in the immediately preceding experiment. For each individual experiment, we considered a dish to be preferred if it was one of the two dishes from which the most honey was consumed. If two consecutive experiments were run in which no compounds were present, bees showed a 47.5% likelihood of returning to a preferred dish. We then calculated the likelihoods of bees returning to their preferred dishes with the compounds. These likelihoods were compared to the control likelihood of 47.5% using the Z-test (alpha=10%), where n is the total number of tests a honeybee returned to any test dish, nP is the number of tests a honeybee returned to a preferred test dish and P is the probability that a honeybee will return to a test dish and is calculated by dividing nP with n. Table 3 show the results obtained on selected candidate compounds. 2-heptone was used as a positive control for a honeybee repellant.

Example 4 Use of Honeybee Repellent in Conjunction with Insecticide

This example illustrates how to use a honeybee repellent disclosed herein to repel honeybees from an area where insecticides have also been applied in order to reduce honeybee mortality and avoid insecticide contamination of honey, beeswax, and other hive products.

At the start of a growing season, an almond tree grower delays the use of a nicotine-based insecticide like Clothianidin and Imidacloprid in order to minimize harmful effects of this insecticide on honeybees while these insects enter his almond tree orchards. While gathering nectar from the flowers of the almond trees, the honeybees pollinate the trees. Subsequently the grower does apply a nicotine-based insecticide like Clothianidin and Imidacloprid to his orchards. At the same or similar time, the grower also applies a honeybee repellent disclosed herein. The grower may periodically apply repellant using the same schedule as that for the insecticide, or one based on the half-life of the honeybee repellent. The grower realizes typical yields of almonds, while at the same time his neighbor, who is a beekeeper, reports that his bee colonies are healthy and he has harvested an excellent yield of honey.

Example 5 Use of Honeybee Repellent to Increase Yields of Seedless Crops
